Oh, so that's why the primordials are supposed to be a threat to the existence as we know it. Nice work!

You make us understand both the magical threat and the brute physicality that could really make a mess of the world--the devastated tower shows us the scale of the primordial, but its destruction appears to have simply been incidental to his path. I believe that this is the first primordial that I've seen that strikes the perfect balance between anthropomorphic deity-hood and the unknowable, alien mindset that governs elementals.
